public class IlvAssociation extends IlvGraphicSet implements IlvPersistentObject
IlvAssociation
contains an IlvLine
that
connects to the center point of two graphic objects.
The connection point for the anchor and callout nodes can be either of
the following:
IlvGraphic
instance.IlvLinkImage
instance that is closest to
the center of the segment lengths.The default values for an IlvAssociation
instance are as
follows:
IlvLine
.IlvLine

object.IlvAssociation
in a simple Java application:
IlvGrapher grapher = new IlvGrapher(); // Creates the origin and the destination nodes IlvRectangle origin = new IlvReliefRectangle(new IlvRect(50,80,40,40)); origin.setBackground(Color.lightGray); grapher.addNode(origin,false); IlvRectangle dest = new IlvReliefRectangle(new IlvRect(250,80,40,40)); dest.setBackground(Color.lightGray); grapher.addNode(dest,false); // Creates the link between the nodes IlvLinkImage link = new IlvPolylineLinkImage(origin,dest,false,null); link.setLineWidth(5); link.setForeground(Color.decode("#40BFBD")); grapher.addLink(link,false); // Creates a composite which groups a label and a left bracket IlvCompositeGraphic callout = new IlvCompositeGraphic(); IlvCenteredLayout cl = new IlvCenteredLayout(); cl.setInsets(new Insets(5,5,5,5)); callout.setLayout(cl); // Creates the bracket IlvBracket bracket = new IlvBracket(); bracket.move(10,10); bracket.setFillOn(true); bracket.setBackground(Color.white); bracket.setWidthRatio(0.5); callout.setChildren(0,bracket); // Creates the text IlvText text = new IlvText(new IlvPoint(),"This is a link annotation"); text.setFont(Font.decode("sansserif-BOLD-10")); callout.setChildren(1,text); grapher.addNode(callout,false); // Creates the association which links the bracket to the link IlvAssociation association = new IlvAssociation(); association.setAnchor(link); association.setCallout(callout); association.setLineWidth(1); association.setForeground(Color.black); association.setLineStyle(new float[]{2.0f,4.0f}); grapher.addNode(association,false);
The following image shows the graphic objects created in the code example:
IlvAssociation
is a custom graphic object, that is, a subclass
of IlvGraphic
. Graphic objects are controlled using an
IlvManager
instance and displayed using one or more
IlvManagerView
instances in a Java Swing application.
